The breeding out of WHEAT resistance to a destructive fungus
The first epidemics of a deadly wheat fungus could have occurred due to widespread cultivation of varieties missing a specific gene.
The loss of a single gene in wheat makes it vulnerable to a fungus called Pyricularia oryzae, which causes a highly destructive disease that emerged in Brazil in 1985 and has since spread to South America, Bangladesh and Zambia. The finding was published in Nature Plants.
